FIGURE F2. CCA-based forecasts for the
SST in a large region in the east-central equatorial Pacific (5°N–5°S,
120°-170°W), expressed as
a standardized anomaly for the upcoming five consecutive 3-month
periods. CCA predictions are based on anomaly patterns of SST, depth of
the 20°C isotherm, sea
level height and sea level pressure. Small squares at the midpoints of
the vertical forecast bars represent the CCA predictions, and the bars
show the one (thick) and two (thin) standard deviation errors. The solid
continuous line represents the observed standardized three-month mean
SST anomaly in the target region up to the most recently available data.
